A few posts above - and a year and a half ago - I was running slightly larger.
A few months ago I picked up an 8.75 Blue Meanie and my 8.75 trucks were sitting on a Polar 1991, so I put Ace AF1 55s on it. Hot damn if I wasn't locking into my grinds on transition better than I had before. I thought it may have been an anomaly, but last week I sized down from 149s to 144s on my 8.3 and I was locking in better than before.
So I was equal to wide, and now I'm narrow to equal.
